I'm a strong proponent of experiential learning outside of the classroom, and Duke in Geneva really offered us some interesting field trips and excursions. We visited the United Nations, we took a trip to Berlin-- which was covered in the expenses of the trip-- with our entire class, and our professors.
One of my favorite components was definitely the relationships that I continue to foster with the friends I met on the program.
I would recommend speaking to previous participants in any programs that you are considering. You can speak with the professors, or make an appointment with the GEO office.
The GEO office is a wonderful resource if you are considering studying abroad. They have so much experience pairing students with the best-match program for their goals, personally, and also their academic and career goals.
